Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates in particular to the end treatment of an automobile door trim in which a thick skin material such as cloth or carpet is pasted together with a thin skin material made of vinyl chloride or the like.

《Prior art and its problems》 Door trims used in relatively high-end passenger cars include a skin material made of a commonly used vinyl chloride sheet, as well as a thick skin material such as cloth or carpet attached to it to add decorative properties. We are trying to further improve this.

Figure 1 shows an example of the door trim.
A thin skin material 3 made of a vinyl chloride sheet is adhered to the surface of the core material 1 via a pad material 2, and a thick skin material 4 made of cloth is attached to the area surrounded by this skin material 3. is pasted.

The peripheral edge of the thin skin material 3 is folded back and adhered to the back surface of the core material 1.

Further, one end portion of the thick skin material 4 reaches one side edge of the core material 1, and this portion is folded back and adhered to the back surface of the core material 1 in the same manner as the thin skin material 3 described above.

Figures 2a and 2b show the cross-sectional shape of the folded end. The thickness a of the portion to which the thin skin material 3 is attached is certainly smaller than the thickness b of the thick skin material 4. Also, when comparing the amount of protrusion a' and b' from the side edge of the core material 1, the amount of protrusion of the thick skin material 4 is larger.

Therefore, when this door trim is attached to the door inner panel, if the side edge is located exactly at the opening/closing end of the door, a gap will be formed corresponding to the difference in thickness between the two skin materials. It was done,
The appearance is not good, and since the amount of protrusion from the core material is large, the difference in level becomes noticeable, which is also a cause of the poor appearance.

<<Purpose of the invention>> The purpose of this invention is to eliminate the gap between the mounting surface and the step on the side edge of the door inner panel, thereby improving the appearance.

《Structure and Effects of the Invention》 In order to achieve the above object, in the present invention, a notch for absorbing the step is formed at the end of the thick skin material at the end of the core material, and is characterized in that a band-like body for increasing the thickness is provided between the notches.

According to the above configuration, the protrusion of the wound end of the thick skin material is restricted by the notch. Further, since the back-adhering part is interposed with a band-shaped body, the apparent thicknesses of the surfaces of the thin skin material and the thick skin material can be matched. Therefore, when this door trim is attached to the inner panel, there is no gap on the attachment surface and there are no irregularities on the side edges, so the appearance of the door trim can be improved.

<<Description of Embodiment>> An embodiment of the present invention will be described in detail below with reference to FIG. 3 and subsequent drawings.

However, the same parts as in the prior art are given the same reference numerals and their explanations will be omitted.

FIG. 3 shows an exploded view of one side of the door trim according to this invention.

In the figure, a notch 10 having a width corresponding to the width of the thick skin material 4 is formed at the end of the core material 1 where the thick skin material is rolled up.

On both sides of the notch 10, a thickening strip 11 made of a pad material or the like is attached to the edge of the back surface of the core 1.

The notch depth of the notch portion 10 is approximately set to a value obtained by subtracting the thickness of the thin skin material 3 from the thickness of the thick skin material 4.

Contrary to the above, the belt-shaped body 11 is set to have a thickness that is the thickness of the thin skin material 3 less than the thickness of the thick skin material 4, and is attached to at least the entire side area of the core material, sandwiching the notch 10. It is worn.

The thick skin material 4 and the thin skin material 3 are attached to the core material 1.
When the thin skin material 3 and the thick skin material 4 are wrapped and pasted together, as shown in FIG. The thicknesses match and are coplanar.

In addition, since the protruding end of the thick skin material 4 from the core material 1 is fitted into the notch 10, there is no step at the boundary with the thin skin material 3, and the end of the thick skin material 4 protrudes from the core material 1. It becomes a continuous outline line.
